RAIL-JOINT.

Application filed. June 4, 1915.

To all wkomit may concern Be it known that T, JEAN BAPTIsTE DU- QUE'ITE, a subject of the King of Great Britain, residing at Ste. Monique, Province of Quebec, Canada, have invented certain new and useful Ti'nprovements in Rail- Joints; and l do hereby declare that the following is a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same.

The invention to be hereinafter described relates to rail joints.

Tn order to more clearly disclose the construction, operation, and use of the invention, reference should be had to the accompanying drawings forming part of the present application.

Throughout the several figures of the drawings like reference characters designate the same parts.

Tn the drawings: Figure 1 is a side view of the joint; Fig. 2 is a top plan view of the same; Fig. 3 is a section on line 3,3 of Fig. 2 looking in the direction of the arrows; and Fig. 4 is a detail view of a key which may be used for unlocking the joint.

The main objects of the invention are to provide a strong, durable, and eflicient rail joint of simple construction and operation which may be produced at a very low cost.

A further object is to provide a joint which is secured by a locking block which may be quickly and easily removed, by suitable mcans, when required.

Referring tothe drawings 1n detall, the

contiguous ends of the rails l and 1 have their web portions thickened, as at 2 and 2 to form blocks of nearly the same thickness as the rail tread. The inner end of the block 2 is cut away to form a socket between the tread and base plate of the rail which snugly receives the inner end of the block 2 which is extended to form a tongue adapted to fit into the socket thus formed. This arrangement securely locks the rail The contiguous rail ends and blocks 2 and 2 are provided with a deep vertical groove extending from the top to within a short dis tance of the bottom thereof. The ends of this groove communicate with cylindrical bores 3 extending from the top to the bottom of the rails, the upper ends of which are enlarged to form inner annular retaining shoulders. A locking block consisting Specification of Letters Patent.

of a web portion 4 and cylindrical end post 5 is adapted to be tightly fitted into the said slot and the bores communicating therewith. The posts 5 are provided, at their upper ends, with enlarged heads 5* adapted to fit snugly into the enlarged upper ends of the cylindrical bores. This serves to maintain the block in a true position. The posts .5 and web d of the block are, of course, of such height as to be flush with the upper surface of the rail tread. The locking block effectually secures the rail ends against lateral or longitudinal movement.

In order that the locking block may be a small bore 6 is provided through the web 4, some distance above the lower edge and at the transverse center thereof. Also, a slot 7 is provided through the outer side of the tongue of block 2, in front of the bore 6. By this means, a key, such as that shown in Fig. ljmay be readily inserted in the bore 6 and the block raised suliiciently to make it possible to get a secure hold on the top thereof so that it can be lifted out of the rails and thus unlock the joint.

It is thought that the construction, operation, and use of the invention will be clear from the preceding detailed description.

Changes may be made in the construction, arrangement, and disposition of the several parts of the invention without in any way departing from the field and scope of the same, and it is meant to include all such within this application wherein only a preferred form has been disclosed.

Having thus fully described my invention, what I claim as new and cure by Letters Patent is:

1. A rail joint comprising the combination of adjacent overlapped rail ends each provided with a vertical bore and a slot from the top surface, and a locking member having end posts fitted into the bores and a web connecting the end posts and fitted into the slots, the bores being formed with annular shoulders and the posts being formed with heads disposed to rest on the shoulders.

2. A rail joint comprising the combination of overlapping adjacent rail ends provided with bores, and slots extending therefrom to the adjacent ends of the rails, and a locking member disposed in the bores and slots, one of the rails being provided with a slot in its web and the locking member being provided with an opening arranged so as to be adjacentthe slot when the locking member is in position. A

3. In zi'rail joint; rail sections having the Web portion of their contiguous ends thickened to form integral blocks, one of saidblocks being cut away at its inner end and the other of said blocks being, extended so as to'fitr into the socket formed by cutting away the inner end of the first menticned block, the said rail ends and blocks being provided with a deep vertical groove and verticalbores communicating with the ends o f said groove, the said extended inner end of the second mentioned block being further provided With a vertical slot through one side; and a locking bolt con- Co pi'es of this patent inay be obtained for sisting of a web portion and end posts carried thereby and adapted to fit snugly into the groove and bores 01' the said rail ends and blocks, the web portion of said locking e block being provided with an opening nor- JEAN 'BAPTISTE DUQUETTE.
